abstract = {Topological spin textures are of great interest for both
fundamental physics and applications in spintronics. The
Dzyaloshinskii–Moriya interaction underpins the formation
of single-twisted magnetic solitons or multi-twisted
magnetic skyrmions in magnetic materials with different
crystallographic symmetries. However, topological
transitions between these two kinds of topological objects
have not been verified experimentally. Here, the direct
observation of transformations from a chiral soliton lattice
(CSL) to magnetic skyrmions in a nanostripe of the monoaxial
chiral magnet CrNb3S6 using Lorentz transmission electron
microscopy is reported. In the presence of an external
magnetic field, helical spin structures first transform into
CSLs and then evolve into isolated elongated magnetic
skyrmions. The detailed spin textures of the elongated
magnetic skyrmions are resolved using off-axis electron
holography and are shown to comprise two merons, which
enclose their ends and have unit total topological charge.
Magnetic dipolar interactions are shown to play a key role
in the magnetic soliton–skyrmion transformation, which
depends sensitively on nanostripe width. The findings here,
which are consistent with micromagnetic simulations, enrich
the family of topological magnetic states and their
transitions and promise to further stimulate the exploration
of their emergent electromagnetic properties.},
